UNITED STATES ELL IOTT LEWIS CHISLING', OF BROOKLYN, NEW YORK.

SUBMARINE RELIEF VALVE.

Application filed October 23, 1925. Serial No. 64,486.

This invention relates to submarine relief valves, an object of the invention being to provide a submarine with improved means whereby communication with imprisoned men in sunken submarines'may be maintained, and also whereby air and food may be supplied as well as gas and liquid removed from compartments of the sub marine. i

A further'object is to provide improved means of this character which are housed within the submarine. leaving the outer wall or surface thereof free from obstruction to interfere with the operation of the submarine.

It is a well known fact that when submarines are sunk from one cause or another many lives have been lost due to the fact that air and food cannot be supplied to the imprisoned occupants, and it. is the broad object of my inventionto so equip the submarine with my improved relief valves that imprisoned men in compartments can be supplied with air and liquid food for an indefinite period, and also communication may be had with them at all times.

While my invention is particularly adapted for facilitating rescue work as applied .to the lives of men, it is also applicable to rescue work as applied to the submarine itself. For example, by employing my 1m proved valves, the water in compartments can be removed and replaced by air or other gas which will assist in raising the submarine.

With these and other objects in Vl8W,- the invention consists in certain novel features of construction and combinations and arrangements of parts, which will be more full hereinafter described and pointed out in t e. claims.

In the accompanying drawings- Figure 1 is a fragmenta y view in elevation of theouter portion of a submarine, showing my improved mechanism as applied thereto;

Figure 2 is a similar view, showing the covering plate removed;

Figure 3 is asimilar view, showing the air lines or pipes connected with the valves;

Figure 4 is an enlarged View in section on the staggered line 4- -4 of Figure 1;

Figure 5 IS a sectional view, more or less diagrammatic, illustrating my invention in connection with a sunken submarine.

1 represents a submarine having water comparti'neuts 2 and compartments 3 for men and machinery. trated my invention in connection with one of the compartments 3, it is obvious that the invention may be applied to any or all of such compartments as well as to the water compartments 2, and I do not wish to be limited in this particular.

Specifically my invention includes a box or casing 4, located inside the submarine, and having flanges 5 at its outer edges secured. preferably by rivets 6, to the outer plate 7 of the submarine. This plate 7 has an opening 8 therein preferably larger than the interior dimension of the box or casing 4 aud con'm'iunicating therewith.

A covering plate 9 is provided to' close this opening and lie flush with the outer plate 7 of the submarine, This covering plate 9 is preferably formed at its edges with webs 10 projecting into recesses 11 in the flanges 5 with bow springs 12 inter-.

posed between the webs 10 and the bases of said recesses 11, tending to force the plate outwardly when the plate is released.

Gaskets 13 are interposed between the inner face of plate 9 and the flanges 5 as well as between the flanges 5 and the submarine outer plate 7, as clearly shown in Figure 4.

The box or casing 4 is formed of an outwardly projecting post 14 having a screw threaded bore 15 receiving a bolt 16. This bolt 16 is; projected through an opening 17 in the covering plate 9, and a gasket 18 is located between the-head 19 of the bolt 16 and the plate -9 so as to make the connection watertight. It will be not-ed that this bolt 16 performs the function of clamping and securing the covering plate 9 in its closed position. v

I also provide the covering plate 9 with air openings 20, normally closed by plugs 21 with gaskets 22 inter osed between the heads of the plugs and t e plate 9. When these plugs 21 are removed they permit a by-pass between the interior of the box or casing and the water surrounding the submarine so as to overcome resistance to the removal of the plate 9.

Within the box 4.- I provide a pair of valves 23 and 24., which may have any suitable means thereon for turning the same, but I have illustrated for the purpose ordinary wrench receiving enlargements 25 on the stems of said valves, so that these valves may be opened by an ordinary wrench.

\Vhilc I have illus- The valves 23 and 24 are connected at their inner ends to pipes 26 and 27, respectively, said pipes projecting through the inner wall of the box or casing 4 and pref erably screw-threaded so as to engage the 1nternal threads in the openings, indicated. 1

Flanges or enlargements 28 are formed on the pipes 26 and 27 with nuts29 located 1nside of the box or casing and co-operating with said enlargements to securely clamp the pipes and the valves in their proper positions. Suitable gaskets 30 are interposed between the enlargements 28, nuts 27 and the wall box or casing 4 to make the junctures Watertight.

The outer ends of the valves 23 and 2 are formed with threaded nipples 31 to receive the ends of couplings 32 and the Hexible pipes or hose 33 and 34. These pipes or hose 33 and 34 may be of any suitable length and have their inlet ends terminating in a relief boat 35, fora purpose which will be hereinafter explained.

While I have illustrated my improved valves as applied to one compartment of a submarine they of course may be applied to any or all of the compartments of a submarine. and I preferably terminate the pipe 26 in the upper portion of a compartment 3 While I extend the pipe 27 to the lower further corner of the compartment, as shown in Figure 5, for best results.

The operation is as follows:

Assuming that the submarine is sunk, as indicated in Figure 5, the diver is lowered into the'water and locates a plate 9 or any desired number or these plates,

course obvious that the plates may be colored or have distinguishing marks thereon which make it easy for the diver to lo-' cate them. When a plate is located, it is simply necessary for the diver to remove this plate 9, but before doing so he first removes any desired number of plugs 21 so as to prevent resistance to the movement of the plate. With an ordinary wrench he can turn the bolt 16 until the latter is released from post 14 and can then remove the plate 9. He then attaches the pipes 33 and 34 to the valves 23 and 24 and open communication is instantly had with the compartment of the submarine.

These pipes may be used as speaking tubes so that conversation may be carried on with the occupants of the compartments and their condition ascertained. If air is needed it will be supplied through one pipe and exhaust through the other, preferably in the as clearly and it is of' marine, and where a compartment contains gas this likewise can be Withdrawn. By the provision of such a valve mechanism I therefore not only prolong the life of the 1m- I also provide means to submarine.

Various slight changes and alterations might be made in the general form of the assist in raising the parts described without departing from my invention and hence I do not limit myself to the precise details set forth but consider myself at liberty to make such slight changes and alterations as fairly fall within the spirit and scope of the appended claims.

I claim:

1. In combination, a submarine having an opening in itsouter plate, a box or casing, flanges onsaid box or casing secured to the inner face of the outer plate of the sub marine adjacent the wall of said opening, said flanges having grooves therein, a covering plate located within the opening flush with the outer plate of the submarine, said plates having webs interlocking with said one of said pipes terminating at the upper portion of the submarine compartment, and

the other adjacent the ment.

2. In combination, a submarine having an opening in' its outer plate, .a box or casing, flanges on said box or casing secured to the inner face'of the outer plate of the'submarine adjacent the wall of said opening, a covering platelocated within the opening, flush with the outer plate of the submarine and engaging said flanges, a relief valve in the box or casing communicating with the interior of the submarine, a central post in the-box or casing, and a bolt projected centrally through the covering plate and screwed intothe' post.
